In this study, a recurrent massive phyllodes tumor of the breast was surgically removed and the grafting was used to repair the local skin defects. A 29-y female patient had recurring breast phyllodes tumor of extremely large size in the chest wall after the excision of a previous tumor. The massive phyllodes tumor was eliminated by completely removing the layers of the skin and tissues above the costal bones with incisal margin being 2 cm away from the tumor lesion. The latissimus dorsi myocutaneous flap, lateral thoracic skin flap, and rectus abdominis myocutaneous flap were grafted to replace the lost tissues due to the surgery. Anti-infection and anticoagulation treatments were used after the surgery. The graft flaps had sufficient blood supply and good blood circulation, and the incisions mostly healed. The outcome of the surgery was acceptable. For the surgical treatment of the massive phyllodes tumor in the chest wall, it is an alternative of choice to use latissimus dorsi myocutaneous flap, lateral thoracic skin flap and rectus abdominis myocutaneous flap in combination for skin grafting.

To solve the issues of costly planting of facility cultivation method and inferior efficacy than wild herbs of Dendrobium officinale, the cliff epiphytic cultivation method was studied. To research the growth, agronomic traits, yield, polysaccharide and alcohol-soluble extract contents were measured on the D. officinale from different water regulation and cliff slope gradients treatments. The results showed that D. officinale epiphytic at 85 degrees-90 degrees cliff and sprayed water 1-2 h x d(-1) at the growing season can get better growth and obtain high yield, and the morphology has no different from wild cliff D. officinale, even in the environments without shade. The contents of polysaccharide and alcohol-soluble extract are closely related to the physiological ages, but significantly higher than the facility cultivation. It is possible that environmental stresses benefit the accumulation of polysaccharides, alcohol-soluble extract and other efficient ingredients.

OBJECTIVECardiotonic steroids (CTS) can bind to Na+, K+ -ATPase to activate complex intracellular signaling cascades regulating the proliferation and apoptosis of cells. The aim of this study was to investigate the effects of ouabain at different concentrations on growth regulation in various kinds of leukemia cell lines and explore the pathogenesis of leukemia, the functions of Na+, K+ -ATPase as a signal transduction conductor and its effects on cell growth.

METHODSUsing the MTT assay, the survival rates of leukemia cell lines were observed 6, 12 and 24 hrs after treatment with 1 or 10 nmol/L ouabain. The expression of Na+, K+ -ATPase alpha1 subunit of leukemia cells was detected by Western blot.

RESULTSThe MTT results showed that ouabain at 1 nmol/L or 10 nmol/L induced proliferation of lymphocytic leukemia B95 and Jhhan cell lines, as well as megakaryocytic leukemia M07e and Meg01 cell lines. Ouabain at 1 nmol/L or 10 nmol/L increased the expression of Na+, K+ -ATPase alpha1 subunit. There were significant differences in the proliferation and the expression of Na+, K+ -ATPase alpha1 subunit of the leukemia cell lines between the ouabain treatment and the blank control groups 24 hrs after ouabain treatment (P<0.05). The proliferation effect of leukemia cell lines was in a direct proportion with the ouabain concentration and incubation time.

CONCLUSIONSNa+, K+ -ATPase plays an important role in signal transductions. Through binding to ouabain, Na+, K+ -ATPase may regulate proliferation of leukemia cell lines of different origins. Ouabain at 1 nmol/L or 10 nmol/L may induce proliferation of lymphocytic leukemia cell lines (B95, Jhhan) and megakaryocytic leukemia cell lines (M07e, Meg01), and the proliferation effect was in a direct proportion with the concentration and incubation time of ouabain.

OBJECTIVEUsing MBEC-Assay to assay minimal biofilm eradication concentration (MBEC) of Galla Chinensis and Nidus Vespae to oral bacterial biofilm. To set up traditional Chinese medicine susceptibility pharmacodynamic empirical study methods of oral bacterial biofilm.

METHODSCariogenic bacteria strains were selected (Streptococcus mutans ATCC 25175, Streptococcus sanguis ATCC 10556, Lactobacillus rhamnosus AC 413, Actinomyces naeslundii WVU 627) in this study. Extraction components of Galla Chinensis were GCE (aqueous extract), GCE-B (30% alcohol extract) and extraction components of Nidus Vespae were NVE1 (95% alcohol extract). (1) To observe oral bacterial biofilm formatiom in MBEC-Device at different time. (2) MBEC-HTP-Assay: The minimal inhibitory concentration (MIC) and minimal biofilm eradication concentration (MBEC) of GCE, GCE-B and NVE1 to oral bacteria strains were determined.

RESULTSOral bacterial biofilm were readily formed on the lid of MBEC-Device under selected condition (observed by SEM). Oral cariogenic bacteria growing as plankton populations were sensitive to GCE, GCE-B and NVE1. To GCE, GCE-B and NVE1, oral cariogenic bacterial biofilm were 2-16 times less susceptible than growing plankton bacteria. GCE and GCE-B were the most effective medicine against oral cariogenic bacterial biofilm. NVE1 were effective in killing oral-bacterial biofilm at relatively high concentration.

CONCLUSIONGCE and GCE-B were effective medicine against oral cariogenic bacterial biofilm. MBEC (minimal biofilm eradication concentration) can provide a relative accurate medicine concentration for clinical test.
